Patent IN-156619-B (IN)
Inventor: PARSLOW MICHAEL WILLIAM
IPC: C11D17/00
Filed: 1983-02-07
Abstract: A method of treating fabrics comprises contacting the fabrics with an aqueous liquor having a pH less than about 7.5, such as between about 5.0 and about 7.0, the liquor containing a cationic fabric softener and lanolin. The liquor is formed by adding to water a composition containing the cationic fabric softener and the lanolin, the concentration of these components in the liquor preferably being from 50 ppm to 500 ppm. The lanolin may be replaced by a lanolin-like material such as derivatives thereof or one or more of the active constituents of lanolin either extracted therefrom or derived from other sources. Preferred ratios of cationic softener to lanolin are 20:1 to 1:20 by weight. A a liquor to flabric ratio of less than 25:1 is preferred. The method generally leads to a deposition of cationic softener and lanolin of less than 0.5% by weight of the fabric.

Abstract: A novel device for mass transfer across a membrane is disclosed, which is particularly suitable for use as a blood oxygenator. The novel device is of the type having a pleated, selectively permeable membrane defining first and second sets of alternating pockets for the flow of a fluid to be treated (e.g. blood) and a treating fluid (e.g. oxygen), and a discrete support screen disposed within each of the pockets of said first and second sets. Of considerable importance is the feature that the support screens are designed to be substantially interdigitated when the assembly of membrane and support screens is held as a compressed stack within the housing of the device. The novel mass transfer apparatus may be utilized as a compact blood oxygenator with excellent gas transfer rates, low pressure drops and negligible trauma to blood components.
